STOP-BOX.

SPECIFICATION forming part of Letters Patent N0. 704,656, dated July 15,1902.

Application filed January 7, 1902. Serial No. 88,812. (No model.)

To all wwnt it may concern/.f

Be it known that I, RANDOLP MCBEE, a citizen of the United States,residing at Vashington, in the District of Columbia, have invented newand useful Improvements in Stop- Boxes, of which the following is aspecificaf tion.

This invention relates to certain new and useful improvements instopfboxes; and ithas for its object, primarily, to provide aconstruction Which will prevent the cover frombecoming detached andlost-such as, for instance, by the influences of frost, dto. It isdesirable that the tops to stop boxes be screwed in position in order toprevent their easy removal, and thus allow dirt and other foreignsubstance to get into the box, yet such tops or caps should be easilyremovable when necessary.

Broadly stated, my invention consists in the provision of a cap or topand the part into which it screws of unlike metals, the part eugagingwith the cap or top' being preferably of brass, although other materialmay be employed, some material that is non-corrodible. Thenon-corrodible material is preferably of brass in the form of a ring,which in one of its forms is seated in a recess or cavity, where it isremovably held in any suitable manner. This ring is interiorly threadedto receive the exterior threads on the depending portion of the cap ortop. This ring is of such a form as to prevent its turning when once inposi-Y tion and is easily removable for replacement or other purposes.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the numerals of reference marked thereon, form a part ofthis specification, and in Which- Figure l is a perspective view of myimproved stop-box, the cover being vshown removed. Fig. 2 is a view ofthe box with the cover in position. Fig. 3 is a top plan view with thecover removed, the ring being in position. Fig. Il is a similar viewwith the ring removed. Fig. 5 is a vertical section on the line 5 5 ofFig. 2. Fig. 6 is a detail view of the cover on a larger scale. Fig. 7is a perspective view of the ring removed. Fig. 8 is `a View, partly inelevation and partly in vertical section, showing a modified form ofconstruction. Fig. 9 is a substantially central vertical section throughthe upper part of a box of a slightly-modified form.

Like numerals of reference indicate like parts throughout the severalviews.

Referring to the drawings, l designates the box proper, which may be ofany of the Well- `known forms, except as hereinafter specified. l.As myimprovements pertain solely to the top portion ofthe box, a detaileddescription of the other portion is not deemed'necessary.

Referring first to the form seen in Figs. l to 7, inclusive, it Will beseen that the box at its upper end is formed with the usual enlargement2, within which is the substantially horizontal annular ange 3, uponwhich is designed to rest the removable ring 4. As seen best in Fig.@this ange is recessed upon its upper face, as at 5, and in the presentinstance is shown as formed with the diametrically opposite enlargementsor cavities 6 to receive the projections 7 on the ring 4. The ring 4 ispreferably of brass, although other non-corrosive material may beemployed, and in this instance it is shown as provided with theVbefore-mentioned projections 7, corresponding in shape to the cavitiesor enlargements 6, so that when in place the ring is held againstmovement Within the enlargement of the box. The ring is screw-threadedupon its inner wall, as seen in Figs. 5 and 7 at 8, and at oppositesides is provided With the openings 9 for the reception of the bolts 10,which are provided with the screw-heads ll, adapted to be seated in thecountersiuks of the said openings, the said bolts passing through theopenings or slots 1l in the opposite faces of the flange 3, as seen inFig. 5, Where they receive the nuts l2. The ring is thus firmly held inplace against vertical or lateral movement, -yet can be readily removedwhen desired.

13 is the cap or cover. -It may be of the usual form, having the wordTater or Gas thereon, as seen in Fig. l, and it is designed to rest uponthe annular shoulder 14, formed at the upper end of the box and providedwith a lug 15 to receive a Wrench or suitable tool whereby it may bereadily IOO turned. The cap or cover is formed with the dependingportion 16, which is exteriorly screw-threaded, as seen in Fig. 6, toengage the threads of thea-ing, as seen in Fig. 5. In practice, the ringbeing secured in position, the cap is placed in position and the threadsof its depending portion engaged with the threads of the ring and thecap or cover then screwed down. The brass of the ring contacting withthe depending portion of the cover or cap keeps the latter from contactwith the iron of the box at that point, and the result is that the coverwill never rust into the ring, but may at all times be relied upon asbeing in condition to be easily removed by unscrewing the same.

The invention is capable of embodiment in a vvariety of forms other thanthat above described. For instance, the ring may be otherwise held inposition. In Fig. 9 I have shown one convenient way. In this form theupper portion of the box is formed interiorly with the ilange 17, havingthe oiset or shoulder 18, the iiange at its lower portionbeinginteyriorly screw-threaded, as seen at 19, to receive the threadedportion 2O of thering 21, the said ring being provided at its upper endwith the exterior annular llange 22, resting upon the shoulder 18, asseen in Fig. 9. The cap or cover is provided with the screw-threadeddepending portion engaging the threads of the ring the same asin theform seen in Fig. 5.

In Fig. 8 is shown another form of ring 23, having the holes 24 for thereception of the bolts or other means which are to secure it inposition, and this ring is formed to receive the'casted threads 25 onthe cap or cover 26, which arevprovided in lieu of thecut threads on thecovers in the other forms in order that the cover may be cast, ifdesired, with the threads instead of the threads being cut as iscustomary in lthis class of devices. The result is practically the same.The rings shown in Figs. 8 and 9 are, like those previously described,formed of brass or some suitable noncorrodible material for the samepurpose.

As will be evident from the above, the stopbox herein describedmay beused for either water or gas and other purposes.

From the above it will be seen that I have devised a novel form ofstop-box capable of manufacture at minimum cost, yet most efficient forthe-purposes for which it is intended,l

and while the structural embodiment of my invention as herein disclosedis what I at the present time consider the preferable it is evident thatvarious changes, variations, and modifications may be made withoutdeparting from the spiritbf the invention or sacrificing any of itsadvantages, and I therefor'e do not wish to be restricted to the detailsof construction herein set forth, but reserve the right to make suchchanges, variations, and modifications as come properly within the scopeof the protectionprayed.

What I- claim as new is- 1. A stop-box having an internal horizontalsupporting-ange recessed upon its upper face, a ring removably supportedin said recess against rotary and outward movement, and a cap having adepending sere w-threaded portion screwed into said ring, substantiallyas described.

2. A stop-box having a iiange with recess with enlargements, a ringindependent of the box and having projections iitting said enlargements,means for detachably securing the ring in position, and a cap or coverhavinga depending screw-threaded portion to engage the threads of thering, substantially as described.

3. As an improved article of manufacture, the stop-box herein described,the same comprising the box proper having enlargement at its outer end,an internal angular horizontal ange Within said enlargement and having arecess upon its outer face with diametrically disposed enlargements, ascrew-threaded ring supported on said iiange and having projectionsttingsaid enlargements, means detachably securing said ringin positionwith its upper face flush with the upper face ofthe lian ge, and a capor cover having screw-threaded depending portion engaged with thethreads of the ring, the screw-threaded engaging portions, being ofdifferent metals, one of which is non-corrodible, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

RANDOLP MCBEE.
